SPECIFICATION forming part of Letters Patent N0. 755,099, dated. March22, 1904.

- Application filed January 24, 1903. Serial No. 140,403. (No model.)

To allwhmn it may concern:

I Be it known that I, CHARLES A. BERTRAND, a

- pose of holding the pieces of leather together with and ride upon theWedge projections upon the side of the box, and an operatingleverpivotally connected to the clamping-bar.

The invention consists also in certain details of constructionhereinafter fully described, and pointed out in the claim.

In the drawings, forming part of this specification, Figure 1 is aperspective view of a holder or clamp constructed in accordance with myinvention. Fig. 2 is a top plan view of one end of a device, the leverand clampingbar being moved to an open position ready to receive thepieces of leather to be held or clamped. Fig. 3 is a similar viewshowing the lever and clamping-bar adjusted to bind against the stripsof leather arranged in the box of the holder. Fig. 4 is a transversesectional view on the line 4 4 of Fig. 3.

In carrying out my invention I employ a long narrow openended'box A,comprising the bottom piece A and the side pieces A said side piecesprojecting above the bottom A, as most clearly shown in Fig.4. .The boxmay be any desired length and width, according to the character of thework to be performed. One of the side pieces A is provided withwedge-shaped projections B, which extend inwardly toward the center ofthe box, and it will be understood that these projections may be formedintegral with the said side or connected thereto in any suitable manner.A clamping-bar C is arranged longitudinally within the box,saidclamping-bar being of substantially the same length as the box, andthis clamping-bar is also provided with wedge-shaped projections D,which are adapted to contactwith and ride upon the wedgeshapedprojections B whenever the clamping-bar is moved longitudinallywithinthe box, and in order to so move the clampingbar I employ a hand-leverE, which is pivoted in a suitable bracket F, attached to the side of thebox and pivotally connected to the clamping-bar by means of a link G.The strips of leather H are arranged longitudinally within the boxbetween the clampingbar and the opposite side of the box, and thehand-lever is then thrown forwardly into the position shown in Fig. 3,and the clampingbar being moved longitudinally the inclined orwedge-shaped projections contacting with and riding upon theWedge-shaped projections upon the side of the box cause the saidclamping-bar to be moved toward the opposite side of the box and tightlybind or clamp the strips of leather and securely hold them in thatposition, and by having theside of the shaped bail K, connected to theclamping-bar adjacent to its free end, and the post or screw K, fastenedto the bottom of the box and arranged Within the bail K, said bailcontacting with the said screw or post and limiting the movements of theclamping-bars. Whenever narrow strips of leather are to be clamped andheld or when the trace is to be held for the purpose of burnishing theedges, a supple- .box and the clamping-bars straight and even mentalclamping-bar L is arranged Within the box alongside the mainclamping-bar, so that the limited inward movement of the clamping-barwill be sufiicient to tightly bind the strips together.

It will thus be seen that I provide an exceedingly cheap, simple, andefiicient device for clamping and holding strips of leather while beingtacked together or While the edges are being burnished.

By making the bail essentially triangular in shape the inclined sidecontacting with the post will serve to draw the clamping-bar away whenthe lever is thrown back to open the devlce.

Having thus fully described my invention,

fied.
